1# 2# $FreeBSD$ 3# 4# The user-driven targets are: 5# 6# universe - *Really* build *everything* (buildworld and 7# all kernels on all architectures). 8# tinderbox - Same as universe, but presents a list of failed build 9# targets and exits with an error if there were any. 10# buildworld - Rebuild *everything*, including glue to help do 11# upgrades. 12# installworld - Install everything built by "buildworld". 13# world - buildworld + installworld, no kernel. 14# buildkernel - Rebuild the kernel and the kernel-modules. 15# installkernel - Install the kernel and the kernel-modules. 16# installkernel.debug 17# reinstallkernel - Reinstall the kernel and the kernel-modules. 18# reinstallkernel.debug 19# kernel - buildkernel + installkernel. 20# kernel-toolchain - Builds the subset of world necessary to build a kernel 21# kernel-toolchains - Build kernel-toolchain for all universe targets. 22# doxygen - Build API documentation of the kernel, needs doxygen. 23# update - Convenient way to update your source tree(s). 24# check-old - List obsolete directories/files/libraries. 25# check-old-dirs - List obsolete directories. 26# check-old-files - List obsolete files. 27# check-old-libs - List obsolete libraries. 28# delete-old - Delete obsolete directories/files. 29# delete-old-dirs - Delete obsolete directories. 30# delete-old-files - Delete obsolete files. 31# delete-old-libs - Delete obsolete libraries. 32# targets - Print a list of supported TARGET/TARGET_ARCH pairs 33# for world and kernel targets. 34# toolchains - Build a toolchain for all world and kernel targets. 35# xdev - xdev-build + xdev-install for the architecture 36# specified with XDEV and XDEV_ARCH. 37# xdev-build - Build cross-development tools. 38# xdev-install - Install cross-development tools. 39# xdev-links - Create traditional links in /usr/bin for cc, etc 40# native-xtools - Create host binaries that produce target objects 41# for use in qemu user-mode jails. 42# 43# "quick" way to test all kernel builds: 44# _jflag=`sysctl -n hw.ncpu` 45# _jflag=$(($_jflag * 2)) 46# [ $_jflag -gt 12 ] && _jflag=12 47# make universe -DMAKE_JUST_KERNELS JFLAG=-j${_jflag} 48# 49# This makefile is simple by design. The FreeBSD make automatically reads 50# the /usr/share/mk/sys.mk unless the -m argument is specified on the 51# command line. By keeping this makefile simple, it doesn't matter too 52# much how different the installed mk files are from those in the source 53# tree. This makefile executes a child make process, forcing it to use 54# the mk files from the source tree which are supposed to DTRT. 55# 56# Most of the user-driven targets (as listed above) are implemented in 57# Makefile.inc1. The exceptions are universe, tinderbox and targets. 58# 59# If you want to build your system from source be sure that /usr/obj has 60# at least 1GB of diskspace available. A complete 'universe' build requires 61# about 15GB of space. 62# 63# For individuals wanting to build from the sources currently on their 64# system, the simple instructions are: 65# 66# 1. `cd /usr/src' (or to the directory containing your source tree). 67# 2. Define `HISTORICAL_MAKE_WORLD' variable (see README). 68# 3. `make world' 69# 70# For individuals wanting to upgrade their sources (even if only a 71# delta of a few days): 72# 73# 1. `cd /usr/src' (or to the directory containing your source tree). 74# 2. `make buildworld' 75# 3. `make buildkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 76# 4. `make installkernel KERNCONF=YOUR_KERNEL_HERE' (default is GENERIC). 77# [steps 3. & 4. can be combined by using the "kernel" target] 78# 5. `reboot' (in single user mode: boot -s from the loader prompt). 79# 6. `mergemaster -p' 80# 7. `make installworld' 81# 8. `mergemaster' (you may wish to use -i, along with -U or -F). 82# 9. `make delete-old' 83# 10. `reboot' 84# 11. `make delete-old-libs' (in case no 3rd party program uses them anymore) 85# 86# See src/UPDATING `COMMON ITEMS' for more complete information. 87# 88# If TARGET=machine (e.g. powerpc, sparc64, ...) is specified you can 89# cross build world for other machine types using the buildworld target, 90# and once the world is built you can cross build a kernel using the 91# buildkernel target. 92# 93# Define the user-driven targets. These are listed here in alphabetical 94# order, but that's not important. 95# 96# Targets that begin with underscore are internal targets intended for 97# developer convenience only. They are intentionally not documented and 98# completely subject to change without notice. 99# 100# For more information, see the build(7) manual page. 101# 102 103# This is included so CC is set to ccache for -V, and COMPILER_TYPE/VERSION 104# can be cached for sub-makes. 105.include <bsd.compiler.mk> 106 107# Note: we use this awkward construct to be compatible with FreeBSD's 108# old make used in 10.0 and 9.2 and earlier. 109.if defined(MK_DIRDEPS_BUILD) && ${MK_DIRDEPS_BUILD} == "yes" && !make(showconfig) 110# targets/Makefile plays the role of top-level 111.include "targets/Makefile" 112.else 113 114TGTS= all all-man buildenv buildenvvars buildkernel buildworld \ 115 check-old check-old-dirs check-old-files check-old-libs \ 116 checkdpadd clean cleandepend cleandir cleanworld \ 117 delete-old delete-old-dirs delete-old-files delete-old-libs \ 118 depend distribute distributekernel distributekernel.debug \ 119 distributeworld distrib-dirs distribution doxygen \ 120 everything hier hierarchy install installcheck installkernel \ 121 installkernel.debug packagekernel packageworld \ 122 reinstallkernel reinstallkernel.debug \ 123 installworld kernel-toolchain libraries lint maninstall \ 124 obj objlink regress rerelease showconfig tags toolchain update \ 125 _worldtmp _legacy _bootstrap-tools _cleanobj _obj \ 126 _build-tools _cross-tools _includes _libraries _depend \ 127 build32 builddtb distribute32 install32 xdev xdev-build xdev-install \ 128 xdev-links native-xtools installconfig \ 129 130TGTS+= ${SUBDIR_TARGETS} 131 132BITGTS= files includes 133BITGTS:=${BITGTS} ${BITGTS:S/^/build/} ${BITGTS:S/^/install/} 134TGTS+= ${BITGTS} 135 136.ORDER: buildworld installworld 137.ORDER: buildworld distributeworld 138.ORDER: buildworld buildkernel 139.ORDER: buildkernel installkernel 140.ORDER: buildkernel installkernel.debug 141.ORDER: buildkernel reinstallkernel 142.ORDER: buildkernel reinstallkernel.debug 143 144PATH= /sbin:/bin:/usr/sbin:/usr/bin 145MAKEOBJDIRPREFIX?= /usr/obj 146_MAKEOBJDIRPREFIX!= /usr/bin/env -i PATH=${PATH} ${MAKE} \ 147 ${.MAKEFLAGS:MMAKEOBJDIRPREFIX=*} __MAKE_CONF=${__MAKE_CONF} \ 148 -f /dev/null -V MAKEOBJDIRPREFIX dummy 149.if !empty(_MAKEOBJDIRPREFIX) 150.error MAKEOBJDIRPREFIX can only be set in environment, not as a global\ 151 (in make.conf(5)) or command-line variable. 152.endif 153 154# We often need to use the tree's version of make to build it. 155# Choices add to complexity though. 156# We cannot blindly use a make which may not be the one we want 157# so be exlicit - until all choice is removed. 158WANT_MAKE= bmake 159MYMAKE= ${MAKEOBJDIRPREFIX}${.CURDIR}/make.${MACHINE}/${WANT_MAKE} 160.if defined(.PARSEDIR) 161HAVE_MAKE= bmake 162.else 163HAVE_MAKE= fmake 164.endif 165.if exists(${MYMAKE}) 166SUB_MAKE:= ${MYMAKE} -m ${.CURDIR}/share/mk 167.elif ${WANT_MAKE} != ${HAVE_MAKE} 168# It may not exist yet but we may cause it to. 169# In the case of fmake, upgrade_checks may cause a newer version to be built. 170SUB_MAKE= `test -x ${MYMAKE} && echo ${MYMAKE} || echo ${MAKE}` \ 171 -m ${.CURDIR}/share/mk 172.else 173SUB_MAKE= ${MAKE} -m ${.CURDIR}/share/mk 174.endif 175 176_MAKE= PATH=${PATH} ${SUB_MAKE} -f Makefile.inc1 TARGET=${_TARGET} TARGET_ARCH=${_TARGET_ARCH} 177 178# Guess machine architecture from machine type, and vice versa. 179.if !defined(TARGET_ARCH) && defined(TARGET) 180_TARGET_ARCH= ${TARGET:S/pc98/i386/:S/arm64/aarch64/} 181.elif !defined(TARGET) && defined(TARGET_ARCH) && \ 182 ${TARGET_ARCH} != ${MACHINE_ARCH} 183_TARGET= ${TARGET_ARCH:C/mips(n32|64)?(el)?/mips/:C/arm(v6)?(eb|hf)?/arm/:C/aarch64/arm64/:C/powerpc64/powerpc/} 184.endif 185.if defined(TARGET) && !defined(_TARGET) 186_TARGET=${TARGET} 187.endif 188.if defined(TARGET_ARCH) && !defined(_TARGET_ARCH) 189_TARGET_ARCH=${TARGET_ARCH} 190.endif 191# for historical compatibility for xdev targets 192.if defined(XDEV) 193_TARGET= ${XDEV} 194.endif 195.if defined(XDEV_ARCH) 196_TARGET_ARCH= ${XDEV_ARCH} 197.endif 198# Otherwise, default to current machine type and architecture. 199_TARGET?= ${MACHINE} 200_TARGET_ARCH?= ${MACHINE_ARCH} 201 202# 203# Make sure we have an up-to-date make(1).
